The casing is provided with a base 23 and a front wall 24,. which is connected to the hase with a sloping section -25"is'" providedf-with an overhanging ang'e 26 that may be used; as a pull the rear wall I0, at one end by a web 2l andnthat the other by a cover plate 28 that issecure'd "to-'1 The internal gear 51 is formed in a ring 59, as illustrated in Fig. l and the ring is secured to the slider 58 by screws t9 and BI The base I5 of the cutting elements is suspended from the hub 39 of the sleeve IB by arms 52 and 63 and the hub 39 is secured to the sleeve I8 by a set screw 65.

The slider 58 is slidably mounted in the lower part of the casing with the edges held in longitudinally disposed grooves 6B on the inner surace-'ofthe rear',plate,III4 and: 6'! on the inner sur- 'fac'e of the frontplate2ll`respectlvely.` 'The front ears 29 in the end of the casing by screvvs 39. Y; The upper edge of the rear Wall I0 is provided with an inwardly extended iiange 3-I' having spaced longitudinally disposed grooves 32 and 33 therein and Washers34 and 35, as shown inv Figs.

-`6 and 7, and which are positionedonthe. sleeve 1`I8 4are positioned to travel in these grooves rwith the opposite sides of the Washers in grooves 36 'and 31 in an inwardlyextended iange 38on the front wall 24. 7

y The rack is positioned'in theange38. of. the

front wall -24 and the gear I 9, which is journaled on the sleeve lIis positioned-to mesh with the "r'ackZI. The rack 22 is formed inthe flange 3I 'of the 'rear wallIU and this rack ist positioned between the grooves 32 and 33 and washers 34- and 35, mounted on the sleeve I8 are positioned with the edges extending into the grooves 32.and 33 yand with the edges onthe opposite side extend-.i| inginto grooves-39 and 31 of a angeonthe upper end of the front wall 24. I

The gearrack 2l which ispositioned above the groove 35`and upper washer '34'1isppositioned to mesh with the upper Vgear I9and: the Vgear frackll 22, in' the flange-3I- is positioned to mesh with the gear 20 on the opposite'side of the housing.

The arms IG` and II Vin which theupper ends of the pins I3 and I4 are carriedexten'd downwardly from the lowerend of a hub 39. on the lower endl:

of the sleeve I8 and as-the sleeve is rotated by the `gears' the arms I6 and I-I withf the-cutting., elements I I and I2 spin around the point of apencil,

shaving the point as villustrated in Fig. :2.
